We look at the division of 1579275 by 804 
The aim is to understand the frequency of 804 in 1579275.

Going ahead to step 1:
The number 804 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 804

Let's proceed to step 2:
When dividing 15 by 804, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 804

Advancing to step 3:
157 divided by 804 is 0 with a remainder of 157.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 157 after subtracting 0 from 157.
Append the next digit (9) from the dividend to 157 and continue with: 1579 / 804

Moving on to step 4:
When dividing 1579 by 804, we get 1 with a remainder of 775.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 804 from 1579 to get 775.
Take the next digit (2) from the dividend and append it to 775, then repeat: 7752 / 804

Advancing to step 5:
If we divide 7752 by 804, we get 9 and a remainder of 516.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 7236 away from 7752, we end up with 516.
Append the next digit (7) from the dividend to 516 and continue with: 5167 / 804

Going ahead to step 6:
When dividing 5167 by 804, we get 6 with a remainder of 343.
Use 6 as the next digit of our solution. 
Result so far: 196.0
Deduct 4824 from 5167 and we're left with 343.
Bring next digit (5) of the dividend behind the 343 and repeat the process: 3435 / 804

Step 7:
The number 804 fits into 3435 4 times, leaving a remainder of 219.
Use 4 as the next digit of our solution. 
Result so far: 1964.0
Deduct 3216 from 3435 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 8:
804 goes into 2190 2 times with a remainder of 582.
Record the quotient 2 as the next digit in the result. 
Result so far: 1964.2
Subtract 1608 from 2190 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Let's proceed to step 9:
804 can be fit into 5820 7 times, resulting in a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 1964.27
The remainder is 192 after subtracting 5628 from 5820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 10:
If we divide 1920 by 804, we get 2 and a remainder of 312.
Record the quotient 2 as the next digit in the result. 
Result so far: 1964.272
Subtract 1608 from 1920 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
When dividing 3120 by 804, we get 3 with a remainder of 708.
Record the quotient 3 as the next digit in the result. 
Result so far: 1964.2723
If we take 2412 away from 3120, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

On to step 12:
804 can be fit into 7080 8 times, resulting in a remainder of 648.
Use 8 as the next digit of our solution. 
Result so far: 1964.27238
Subtract 6432 from 7080 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 13:
6480 divided by 804 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 1964.272388
Deduct 6432 from 6480 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The quotient of the division is 1964.272388, and the remainder is 4.8e-06.
